RAILWAY-FROG.

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed April 22, 1918: Serial No. 229,912.

To all 'whom it may concern:

Be it known that I, BENJAMIN B. Bn'r'rs, a citizen of the United States, and resident of St. Louis, State of Missouri, have invented new and useful Improvements in Railway-Frogs', of which the following is a specification containing a full, clear, and eX- act description, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to certain new and useful improvements in railway frogs, which has for its special object the employment of a pivoted frog point which is controlled in its movement by a guard lever, or tongue, which is operated by the movement of the rolling stock.

Another special object is the provision of means which are actuated by the flanges of the wheels to line up the frog before the wheels reach the frog point.

Another special feature of my improvement is to so construct the guard lever, or tongue, that it may also act as a rerailing device, should the wheels run ofi' of the track in crossing the frog.

In the drawings,

Figure 1 is a top plan view of my invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a longitudinal section taken on the line 88 of Fig. 1.

Fig. l is a bottom plan view.

Fig. 5 is a view similar to Fig'l, but illustrates the operating levers in dotted lines.

Fig. 6 is a transverse section taken on the line 6-6 of Fig. 1 looking in the direction of the arrow.

Fig. 7 is a transverse section taken on the line 7 -7 of Fig. 1 looking in the direction of the arrow.

Fig. 8 is a transverse section taken on the line 8-8 of Fig. 1 looking in the direction of the arrow.

Fig. 9 is a top plan view of the operating device for the switch point frog, part of the same being broken away.

Fig. 10 is a side elevation of the guard lever, or tongue.

Fig. 11 is a top plan view of the same.

Fig. 12 is a side elevation of the endV of the frog point with part of the same being broken away.

Fig. 18 is a top plan view of the same.

Referring to the drawings, 14 indicates the body portion of my improved frog, which is cast integral. The said body portion is provided throughout its length with a series of perforated plates, or ears, 15 for thereCeptiOn of spikes to hold the same in position. Near one end of the body portion, the same is provided with flanged portion 16, provided with spike openings also adapted to receive spikes for holding the frog in place. The frog, as previously stated, is cast in one piece and is in effect hollow on its underneath portion 17 to receive the operating levers.

Cast integral with one end of the frog are rail sections 18, to which rails may be secured by fish plates in the ordinary manner.

The opposite end of the frog is provided with an extension 19 and a plate 20.

21 indicate rail sections which are bolted to the extension 19 by means of bolts 22. The extension 19 forms a continuation of the elevated portion 23 of the frog.

Formed integral with the frog on each side of the portion 23 are guards 24. These guards are spaced apart sufficiently to pei'- niit the passage of the wheel flanges between them and the portion 23.

Formed through the frog and beneath the portion 23 and the guards 21 are openings, or pockets 25, in which is located a pair of beveled projections 26, which project upwardly into the wheel Harige openings 27, one being located in each wheel flange passage so as to be operated upon by the flanges of the wheels. rlhese projections are mounted on a curved bar 28 which is carried by a lever 29.

The lever 29 is pivotally mounted on a stud 80 formed integral with the frog, having one of its arms carrying, as stated, the bar 28, and its other arm pivotally mounted on a stud 31 carried by the pivoted frog point 82.

One end of the pivoted frog point 32 is pivotally secured adjacent to the portion 23 by means of an integral stud 33. Formed in the frog is an opening 34, in which the stud 31 is adapted to travel.

Pivotally mounted at one end of the frog is a guard lever, or tongue 34, one end of which is provided with a pin, or lug, 85, adapted to be inserted into a suitable opening in the frog and held in position by a cotter pin 36. The opposite end of the guard lever, or tongue, 81 is provided with a pin 37 which passes throughthe frog and on which pin 37 one arm of a lever 38 is mounted.

Lever 38 is pivotally secured to the frog on a pin, or stud 39a. One arm of the lever 38 is pivotally mounted on the stud 31.

From the foregoing description, the operating of lever 29 operates the frog point 32, and when the lever 29 and the frog point 3-2 are moved, the lever 38 is moved, and, consequently, the guard lever, or tongue As previously pointed out, these levers and their connections are housed in the Vbody of the frog, as illustrated in Figs. 3l and 4.

Formed integral with the frog on each side of the pivoted guard lever, or tongue, 34 are guards 39 which terminate on their inner ends with curved recesses or abutments 40 in which the point of the frog point is adapted to be seated. Y

The frog point `is provided with recesses or cutaway portions 41 for the purpose of preventing dirt or foreign substances from becoming' lodged in the recesses or abutments 40.

The pivoted guard lever or tongue 34 is provided withV a groove 42 in which the flange of the wheel may ride in the operation of rerailing a car moving in the direction of the frog point, in which case it is only necessary to shift the Wheel over by means of blocks or any suitable device until the flange comes Vin line with the groove. This guard lever or tongue, by being so constructed, may also be used as a replacer, if the wheel should becomedisplaced, that is, a replacer for the wheels moving in the direction of the frog point.

As previously pointed out, the projections 26y are mounted in the path of travel of the car wheel flanges and are operated by the travel of the anges over the same and will cause a* movement of the frog point 32 through the lever 29 before the wheels reachV the frog point. In other words, before the load can reach the pivoted frog point, the frog will be lined up, or the frog point 32 be operated upon to locate the same in its proper position.

The frog point is automatically operated by the operation of the projections 26, and when the frog point is operated in one direction by the system of levers previously described, the pivoted guard lever, or tongue is operated in the opposite direction; and also the operation' of the pivoted tongue, or guard lever, in one direction will operate the frog point automatically in the opposite direction. A movement of the rolling stock in one direction past the pivoted guard lever, or tongue, automatically controls the operation of the frog point, whereas the movement of the rolling stock in the oppositev direction past the projections 26 will operate the frog point in one direction and the pivoted guard lever in the opposite direction.

The frog point 32 is provided with a guard 43 which covers the elongated slot in which the pin, or stud, 31 travels.

Having fully described my invention, what I claim is:

1. A railway frog comprising a pivoted frog point and a pivoted guard lever, a connection between said frog point and lever whereby the operation of one in a given direction will cause the other to be operated in the opposite direction, and a projection located in the path of travel of the wheel flange and adapted to be actuated by the Wheel flange for operating the frog point, and, consequently, the guard lever. l

2. A railway frog cast integral and proy vided on one end with guards and connections for rails, and on the other end with rail sections and tread sections forming a continuation of the rail sections, a pivoted frog point, a pivoted guard lever and a prol jection mounted in advance of the pivoted frogand in the path of travel of the wheel flanges, and a connection between said projection, pivoted frog and guard lever whereby the operation of eitherwould automatically operate the other two.
